7.2.2. Parameterization (configuration) procedure
Recommendations for the configuration change
Measurement circuits, energy calculation algorithms, type of the temperature sensors, value of pressure
for thermal energy calculation and numbers of flow sensors should be checked according to individual
heat meter data (see Paragraph 13).
If are required by measurement circuit, other parametres of a configuration should be made active and
entered:
The additional flow inputs (V3 and V4) are activated, the inputs parameters values corresponding
values of the water meters which will be connected to these inputs are set: pulse value, minimal and
maximum flow rate, type of input pulses and the minimal possible pulse frequency period.
The additional pressure inputs are activated, the inputs parameters values corresponding values of the
pressure sensors, which will be connected to these inputs are set: limits of current,
minimal and maximum pressure orresponding to current limits.
The additional tempertature input (T3) are activated. If it is used on regulation mode „On2“ –
it is obliged to make active the temperature measurement channel T3 for measurement of outdoor
temperature.
The individual parameters for a pulse / frequency output should be selected from the list
The regulation function are activated, operating mode is selected from list, and the parameters values
are entered.
If necessary a customer number is entered.
The communication interfaces settings are entered: M-bus adress, data transfer rate, parity.
Report printing language and communication with the printer interface type are selected from list
If necessary real time clock and calendar readings are corrected
The suggested next battery replacement date is set: (or current date plus 12 years for mains power supply
version). Suggested battery replacement date is calculated by adding estimated battery operation time to
the current date. Estimated battery operation time is given in the Table 7.2:

Configuration of heat meter is possible via optical (or Wire) interface and in conjunction with the
specific configuration programme.
7.3. Setting up jumpers
For battery supply:
If voltage 3,6 V from the pin “19” and “22” is used to power extra flow sensors V3 and V4, the
jumper (beside terminal block) should be conjunct.
For mains supply:
If voltage 3,6 V from the pin “19” and “22” is used to power extra flow sensors V3 and V4, the
jumper (beside terminal block) should be compulsory disjunct.
If the device is equipped with universal interface module (including M-bus, CL, RS-232 interfaces
and two current or pulses outputs):
-
M-bus, CL or RS-232 interface is activated by plugging in the jumpers “CL – M-bus – RS-
232” in such way, that required interface type appears beside the terminal pins “46,,,48”.
Marking on the jumper board will show the functional description of the pins.
